Note that the prices listed above for new Surface Book models are promotional deals until November 28. These new models are usually priced at:* $1,499 | ¹ $1,899 | ² $2,099 | ³ $2,699

Microsoft's store listing for the refurbished Surface Book models somewhat overstates the savings that you can expect over a new device. For example, it claims that you'll save $440 on the entry-level Surface Book - but that doesn't take into account that it's currently offering $250 off that brand new model; so in fact, the difference between the new and refurbished models is far smaller, at $190.

The additional savings on the refurbished Book and Pro 4 models ends today, November 28. But even after those deals have ended, the refurbished models will still offer chunky savings compared with the cost of buying brand new. The refurbished entry-level Pro 4, for example, is usually priced $260 (29%) below its new counterpart.
